[Renfro, Michael]

Did Diego's suggestion from [1] not help narrow things down?

I'm using slurm15.08.11, when I submit several 1 gpu jobs, slurm doesn't allocate nodes using compact strategy. Anyone know how to solve this? Will upgrading slurm latest version help ?

For example, there are two nodes A and B with 8 gpus per node, I submitted 8 1 gpu jobs, slurm will allocate first 6 jobs on node A, then last 2 jobs on node B. Then when I submit one job with 8 gpus, it will pending because of gpu fragments: nodes A has 2 idle gpus, node b 6 idle gpus

Thanks in advance!
